American Mastersopens its 27th season with the story of African-American gospel singer and guitar virtuoso Sister Rosetta Tharpe (March 20, 1915 – October 9, 1973). One of the most influential musicians of the 20th century, Tharpe may not be a household name today, but the flamboyant superstar, with her spectacular playing on the newly electrified guitar, played a pivotal role in the creation of rock ’n’ roll. Emmy®-winning filmmaker Mick Csáky uncovers her life, music and lasting influence in American Masters Sister Rosetta Tharpe: The Godmother of Rock & Roll, premiering nationally Friday, February 22 at 9 pm (ET) on PBS (check local listings) in honor of Black History Month.

Southern-born, Chicago-raised and New York-made, Sister Rosetta rose from poverty to become one of the world’s most popular gospel singers and the first to cross over successfully into mainstream popular music. She introduced the spiritual passion of gospel into the secular world of rock ’n’ roll, inspiring some of its greatest stars, including Chuck Berry, Elvis Presley, Jerry Lee Lewis, and Little Richard. A natural-born performer and a rebel, “She could play the guitar like nobody else … nobody!” says Lottie Henry, a member of Tharpe’s back-up vocal group The Rosettes. “Elvis loved Rosetta Tharpe,” attests Gordon Stoker of The Jordanaires, who performed with both Sister Rosetta and Elvis. “Not only did he dig her guitar playing but he dug her singing too.”

The child of poor cotton pickers, Sister Rosetta was born in Cotton Plant, Ark. At the age of six, she was taken by her evangelist mother Katie Bell to Chicago to join the Church of God in Christ, where she developed her distinctive performing style. In 1938, at the age of 23, she briefly left the church for show business, causing huge controversy when she performed songs laden with sexual innuendo in New York City venues such as the famed Cotton Club and Café Society, where she immediately became a favorite of both Cab Calloway and Duke Ellington. However, Sister Rosetta soon returned to her gospel roots and performed in packed churches and theatres throughout America and Europe, becoming one of America’s most distinctive recording stars on radio and television during the 1940s, 1950s and 1960s.
